Tolerance and Acceptability of an Oral Nutrition Supplement

The goal of this study is to learn whether a new oral nutritional supplement is acceptable to adults who are malnourished, or at risk of malnutrition, and need nutritional support. The main questions it aims to answer are: * Do participants tolerate the supplement without stomach or bowel problems? * How much of the prescribed supplement do participants take each day? * How do participants rate the taste, texture and overall experience of taking the supplement? Researchers will also record any side effects. Participants will: * Take the supplement every day for 7 days, as prescribed by their dietitian * Keep a daily diary of how much they take and any stomach or bowel symptoms * Complete a short questionnaire about the supplement and have a review with the study team on Day 7
